The TV "science guy" will continue his crusade against climate-change deniers Sunday on "Meet the Press" by debating Marsha Blackburn, the Republican congresswoman who serves as the vice chair of the House Energy & Commerce Committee, according to TalkingPointsMemo.com.

The former host of the popular 1990s TV show "Bill Nye the Science Guy" took on creationist Ken Ham earlier this month in a debate over the origins of humanity at the Creation Museum in Petersburg, Kentucky.
